COMPOSITIONS COMPRISING INORGANIC PARTICLES |
摘要 |
Floccular compositions comprising ultrafine inorganic particles having maximum particle dimensions of from 0.5 to 3000 (preferably 2 to 1500) nm combined with a size-stabilizer which is a lyophobic substance with lyophilic activity on its surface and also comprising a polyelectrolyte flocculating agent attached to the combination. The size-stabilizer protects the ultrafine particles against agglomeration during formation of the flocculates and the mixing of flocculates into various materials such as plastics, inks, paint or refractory materials. Also a method for making the flocculates from colloidal dispersions of particles, size-stabilizers and flocculating agents. The flocculates are particularly useful with particles of metals of the coinage and transition groups for making transparent coloring agents. Also materials containing the ultrafine particles. |
